Goals

Schedule

End of Nov 2014, write plan and receive feedback.

Before end of 2014, execute the first step of the import.

Import Data (Stage 1, Vantaa)

Background

As all the municipalities have different data formats, we are planning to separate the import in three stages based on the municipality. The source dataset is of very good quality because the same data is used for calculating the property tax (stakeholders have good reasons to have the data correctly).

Import Type

Step 2, Data that does overlap fully with existing buildings and where only tagging is added.

Step 3, Data that overlaps partially, and which has to be imported manually.

Data Preparation (Step 1, non-overlapping data)

Data Reduction & Simplification

Before the import can be started, the alignment of roads in OSM that overlap with buildings from the import must be fixed. The alignment using both Bing and NLS.fi orthophotos was completed in 2014-10 (mostly by user ij_).

The data is then reduced to only the buildings that do not overlap with already existing buildings as described in the workflow.

Plot ID

None

municipality-area-village-plot (might be replaced by the national permanent building id before the import)

OSM Data Files

Data Preparation (Step 2, fully overlapping data)

Data Preparation (Step 3, partially overlapping data)

Data which is not consistant between both datasets has to be imported manually.

Import Data (Stage 2, Espoo)

Background

As all the municipalities have different data formats, we are planning to separate the import in three stages based on the municipality. The source dataset is of very good quality because the same data is used for calculating the property tax (stakeholders have good reasons to have the data correctly).
